Displacement equation
Displacement equation
Displacement (s) equals initial velocity (v₀) times time (t) plus one-half times acceleration (a) times time squared (t²).
Final velocity equation
Final velocity equation
Final velocity (v) equals initial velocity (vâ‚€) plus acceleration (a) times time (t).
Area under velocity-time graph
Area under velocity-time graph
Represents the change in position of the object during that time interval.
s = v₀t + 1/2at²
s = v₀t + 1/2at²

Study Notes
Uniform Acceleration
- The equation for displacement of an object moving with uniform acceleration is $s = v_0t + \frac{1}{2}at^2$
- The relationship between final velocity (v), initial velocity (vâ‚€), and acceleration (a) for an object with uniform acceleration is: v = vâ‚€ + at
- The area under the velocity-time graph represents the total displacement of an object with uniform acceleration
- The equation $s = v_0t + \frac{1}{2}at^2$ represents the displacement of an object in uniformly accelerated motion
- In uniformly accelerated motion, the final velocity (v) is related to the initial velocity (vâ‚€) and acceleration (a) by the equation: v = vâ‚€ + at
